The other end of each clamping dog extends through an aperture 19 in the rib 7 of one of the clamping members and is screw-threaded to receive a clamping nut.15. Iwill employas many of these clamping devices as necessary*but for ordi nary purposes it will be sulhcient to clamp the reenforcing membersto the .PQlBSJ t .3 1 9mb just above the earth and'again at a point' .lto 5 hasa groove 24 formed on its inner face and extending longitudinally thereof.

At each point two such clampingdevicesare employed, one-1on each sldeaw g In order tostrengthen the structure I will preferably reenforce or thicken the ribs7 at the points where the dogs 12 pass: therethrough as shownat 16. The reenforcing members are also shown as'having the ribs 7 thickened near the-lower end as shown at 17, eachQthickened portion 17 being provided with apertures19 to receive'theclamping do s. I

l vhen the reenforcing members-are to be applied to a weakened pole-after it has been set'said members will be driven into the earth on each side of'the pole and when they have been drivento the proper depth theclamping means will be applied. This may be; done by placing the plates 11'. in position against the pole, inserting the screw-threaded ends of the clamping dogs through theapertures 19 and applying the nuts thereto'sufficient to hold the dogs in p'laceand then inserting the noses 13 of the dogs through the appropriate apertures 14 in-theplates 11 and driving the dogs home. After thisfisdone the nuts 15 are tightened so as to tighten the clamps firmly about the pole. Inthis way the clamps, not onlyclamp the reenforcing members to the pole but they are-interlocked with or anchored to the pole so as toprevent the pole from turning.

I have shown the upper end of tlie reenforcing member as thickened somewhat as illustriated at so as to provide a sort'of head portion which may be struck by a sledge hammer or pile driver for drivingthe re-' enforcing member into'place. Ifthe reen- ,forcinginembers are to be applied to'th'e pole then I will also preferably before it is ,set
